Error ADMN0022E (Access is denied because of insufficient or empty credentials) when working with WAS ISC
I have a Connection environment installed for a customer and I have always started and stopped the servers using the ISC.
All of a sudden I could not do that anymore and got the ADMN0022E error in the SystemOut.log. I had to start and stop servers and nodeagent manually from the command line.
A quick check with my friend Andrea Fontana gave me the solution. For whatever reason the administrator credentials in the file soap.client.props, located in profiles/Dmgr01/properties were blank.
I filled in the correct values, synced the nodes and the problem was solved
